Phase 1 of this cross-sectional study aimed to compare hair lead concentrations and establish the determinants of hair lead levels in 149 occupationally exposed individuals versus 177 non-occupationally exposed controls in the Lebanese population. In addition to a standardized questionnaire, lead concentration was measured by atomic spectrophotometry. A 5-6-fold difference in hair lead concentration was found between occupationally exposed and non-exposed individuals (23.60 ppm versus 4.33 ppm). Professional exposure, particularly working in petrol refining and gasoline stations, had the highest correlation with lead exposure. In non-exposed individuals, male sex, non-Lebanese nationality and urban worksite correlated with higher hair lead concentration.
这项横断面研究的第一阶段旨在比较149名职业暴露个体与177名黎巴嫩非职业暴露对照者的头发铅浓度，并确定头发铅水平的决定因素。除了一份标准化问卷外，还通过原子分光光度法测量铅浓度。职业暴露和非暴露个体之间的头发铅浓度存在5至6倍的差异（分别为23.60 ppm和4.33 ppm）。职业暴露，特别是在炼油厂和加油站工作，与铅暴露的相关性最高。在非暴露个体中，男性、非黎巴嫩国籍和城市工作场所与较高的头发铅浓度相关。
